Abstract: An accommodation unit includes: a casing that: stores trays each storing an optical fiber, and includes an insertion opening into which the trays are inserted to be arranged in an up-down direction; and support members disposed in the casing, each of the support members slidably supporting a lower part of each of the trays, and each of the support members including: a pair of arm parts disposed apart from each other in a left-right direction orthogonal to a slide direction of the trays and the up-down direction; and a projection that is disposed on each of the arm parts in a vicinity of the insertion opening, and contacts an upper part of each of the trays under each of the support members.

Abstract: An optical fiber protective unit includes: a reticulated tube having openings that are reticulately formed, the reticulated tube being configured to accommodate a plurality of optical fibers inserted through the reticulated tube; a tubular member disposed inside the reticulated tube, the tubular member being configured to accommodate the plurality of optical fibers through the tubular member; and a cylindrical member attached to an end part of the reticulated tube. The cylindrical member has an inner diameter that is larger than an outer diameter of the tubular member.
